Description

This course is the fifth in a complete series covering the Juniper Networks JNCIA-Junos certification track, providing you with the skills and knowledge required to pass the JN0-102 exam. In this course, Juniper Networks JNCIA-Junos (JN0-102): Operational Monitoring and Maintenance, you will first learn how to monitor the Juniper system and chassis status with the CLI regardless of the hardware platform. Then, you will move on to monitoring interfaces using the ‘monitor interface’ command. This is a really powerful command that allows you to monitor interface statistics and traffic in real-time. After that, you will look at the network troubleshooting tools - ping and traceroute. You are probably familiar with these already, but you’ll take a look at some options you have from within Junos to extend their functionality and you’ll learn about a couple of the network utilities that are also built into Junos - namely telnet and SSH clients. Finally, you’ll look at steps involved in the process of recovering the root password. As with all the courses in this series, there will be plenty of time spent on the command line demonstrating all the commands covered to cement your knowledge. When you’re finished with this course, you will have taken another step towards gaining Juniper Networks JNCIA-Junos certification.
